The phrase “levels of mind” is most commonly used in basic psychology and personal development to refer to three main levels: conscious , preconscious/subconscious , and unconscious mind.

Because your question says “which of the following,” it’s probably from a multiple‑choice item. In those questions, the correct “levels of mind” are usually:

  • Conscious mind
  • Preconscious (or “subconscious”) mind
  • Unconscious mind

Quick Scoop: What each level means

  • Conscious mind – What you’re currently aware of: thoughts, perceptions, and feelings you can notice and describe right now.
  • Preconscious / Subconscious mind – Information that is not in awareness this moment but can be brought into awareness fairly easily (like what you had for dinner yesterday or your phone number).
  • Unconscious mind – Deep wishes, memories, and conflicts that normally stay outside awareness yet still influence your behavior, dreams, slips of the tongue, and emotional reactions.

So, if your options include these three terms, those are the ones that count as “levels of mind.”
